Hydrangea is native to some parts of Asia, North America and was extensively incorporated in traditional Native American medicine. Wild hydrangea is known as ‘seven barks’ and is the most commonly used for medicinal purposes from the array of seventy five different species in the genus. It is the roots that are harvested for their properties and can be used in a variety of different ways. Each layer of bark has a different colour with a tendency to peal.
